PUMP.

SPECIFICATION forming part of Letters Patent N o. 337,402, dated March9.1886.

Application led December 2, 1885. Serial No. 184.528. (No model.)

To @ZZ whom it may concern:

Be it known that I, PATRICK D. HINEs, a citizen of the United States,residing at Summit Station, in the county of Licking and State of Ohio,have invented a new and useful Improvement in Pumps, of which thefollowing is a specification.

My invention relates to improvements in double-cylinder pumps; and theobjects of my improvements are to produce a double-cylinder pump adaptedfor use in pumping the water either from the top or bottom of a well, orto draw water from both points. I accomplish these objects in the mannerillustrated in the accompanying drawings, in which- Figure l is avertical section of my improved pump, and Fig. 2 is a front elevation ofthe same.

Similarletters refer to similar parts throughout the several views.

A represents the stock or main body of the pump, having a barrel, b, anda barrel, c. The barrel b is of the usual length, and may be continuedto the required length, which is preferably near the bottom of the well,by joining to that portion of the stock, in the usual manner, a secondstock. The barrel c extends only a short distance below the platform ofthe well, and has its lower end closed. At a short distance below thetop of the pump these two barrels b c are made to communicate by meansof a transverse hole or cut eX- tending through the partition dividingthe barrels. The barrels are each provided with the usual plunge-rod,having a sucker and valve on the lower end thereof.

The pump-handle g is made to project outwardly from above the top of thepump, and

is pivoted or hinged to a bolt, h, made to eX-' tend between twoupwardly-projecting plates, m, secured to the front and rear sides ofthe stock. The handle g is provided at points immediately above thebarrels b c with vertical slots, within which are pivoted the upper endsof metal hinging-plates 7c by means of short transverse bolts 'L' i',the lower ends of said plates 7c being hinged or pivoted to the upperends of the plunge-rods d d.

. Projecting outwardly through the side of the stock from a point nearthe bottom of the cylinder or barrel c and opening therein is a Shorttube, p, having on its inner end a valve,

0, of any well-known form, and having fitted over its outer projectingend the upper end of a lleXible pipe, c. This pipe c, which may be ofany desired length, extends downward, and has secured to its lower end,by means of a ring and staple, a block or suitable float, f.

A spout, n', of the usual form, is made to project outwardly from thefront side of the pump at a point opposite the center of the transverseeut n, with which it connects.

The pump being constructed as above described, the operation of thehandle g in the usual manner will cause the plunge-rods to rise and fallalternately, the rod d operating to draw the water in the usual mannerfrom near the bottom of the well, the rod d operating to draw only thesurface water, the flexible pipe e, through which the surfacewaterpasses to the cylinder 0r barrel c, being kept from sinking but slightlybelow the surface of the water by means of the iioat f.

It is a well-known fact that at times the surface-water in a wellbecomes stagnant and unfit for use. This stagnant surface-water may bereadily pumped oli' without disturbing the deeper water by withdrawingthe bolt z', thus uncoupling the rod d from the handle, and allowing therod d to be operated alone. The water drawn into either cylinder isallowed to escape through the cut n and out through a common spout, n.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, isd

A double-cylinder pump having one barrel upon a higher level than theother, in combination with a flexible pipe connecting with the lower endof the shorter pump-barrel,and a oat secured to the lower end of saidflexible pipe, substantially as and for the purpose specified.
